Causa Prima Raises $20M Seed to Build Agent-to-Agent AI for B2B Payments

Delaware-based startup Causa Prima raised a $20M seed round led by Base10 Partners to expand its agent-to-agent AI platform for B2B payments. The system is designed to handle the handoff between companies, deploying AI agents to negotiate directly with suppliers' agents to resolve billing disputes and speed up invoice approvals. The company monetizes the platform by taking a cut whenever its agents successfully negotiate early payments between buyers and suppliers. The new funding brings Causa Prima's total raised to $30M, which it plans to use to open a New York office and expand its 25-person team into the United States. "Every dollar going into automation today assumes the bottleneck sits inside one company. Causa Prima is building for the handoff between companies." — Rexhi Dollaku
